Creating a new column using the contents from another cell.

Hi TimTeska,
you can't call value from another row directly (there are of course ways how to do it), but you can call line from previous step

Source (previous step):

Added custom column:

Hi TimTeska ,

Please try:

Text.BeforeDelimiter(#"Changed Type"{3}[Column1],",")

Advanced editor:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjTSN9M3MjAyVjA0tzI2UtJRQkGxOtFKjk7OCs75uQWJeZXYpINLk5zz84rzczJTEktSUxSCS3NzE4sqFYJSC/KLShQ0IHRmXromNt0gq+Odc/KLU+MDDXUUnIMNDAyM4oNS0zPz8+K98rwU3B0dAzA0xgIA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t, Column5 = _t, Column6 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}, {"Column3", type text}, {"Column4", type text}, {"Column5", type text}, {"Column6", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Period", each Text.BeforeDelimiter(#"Changed Type"{3}[Column1],","))
in
    #"Added Custom"
